🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the tail lamp screws

• Open the tailgate.
• On the tail lamp you’re working on, use a Phillips screwdriver #2 to remove the two screws on the inboard edge (the side closest to the tailgate opening).
• Put the screws somewhere safe so they don’t fall into the bumper area.

Step 2: Pull the tail lamp housing straight back

• Hold the tail lamp housing with both hands and pull it straight rearward (straight back).
• If it feels stuck, use a trim clip removal tool to gently pry at the edge—go slow so you don’t crack the lamp.
• Tip: Wiggle gently; don’t twist hard.

Step 3: Remove the turn signal bulb socket

• Find the turn-signal socket on the back of the tail lamp (the socket that matches the turn-signal section of the lens).
• Twist the socket counterclockwise about 1/4 turn, then pull it out.
• (A “socket” is the plastic holder the bulb locks into.)

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Put on nitrile gloves and push the new bulb straight in until fully seated.
• If the bulb is glass, avoid touching it directly; use the clean microfiber towel if needed.

Step 5: Protect the connection and reinstall the socket

• Apply a very small amount of dielectric grease to the socket seal area (not on the bulb glass).
• Insert the socket back into the tail lamp and twist clockwise 1/4 turn until it locks.

Step 6: Reinstall the tail lamp housing

• Line up the tail lamp’s locating pins with the body grommets, then press the housing straight in by hand.
• Reinstall the two screws using the Phillips screwdriver #2 and snug them down.
• Do not overtighten—plastic housings can crack.

Step 7: Repeat on the other side

• Repeat Steps 1–6 for the opposite tail lamp so both rear turn signal bulbs are fresh.
• Tip: Replace in pairs for matching brightness.

✅ After Repair
